DNA MOTORING CBE-IS300-NRT Stainless Steel Cat Back Exhaust System [Compatible with 01-05 IS300 Altezza XE10]

Upgrading vehicle’s exhaust system is a great way to build horsepower, free up trapped torque, and improve upon restrictive factory systems. The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle. The net result is lower auto exhaust backpressure, more horsepower, more torque, and a much better sound.

1 x Catback Exhaust System

From the brand

Key Features

Compatible with your IS300/Altezza XE10 from years 2001–2005.
Full stainless steel cat-back system, designed to reduce backpressure and improve exhaust efficiency.
Polished muffler finish and a rolled tip for a standout appearance.
Straight-through muffler path and larger diameter piping than factory to enhance flow and produce a deeper tone.

Installation & Fitment Notes (so you don’t yell at me later):

While marketed as bolt-on, some users report fitment issues — hangers out of place, tip not aligned perfectly with bumper cut-out, possible need to grind/move a hanger. Reddit+1
Due to the deeper tone, if you do a lot of highway cruising expect more cabin sound than stock.
Verify that the factory mid-pipe and catalytic converter are in good shape; this cat-back will require a decent mid section to shine.

Why Choose It

If you’re building your IS300/Altezza and want that JDM aesthetic and sound without dropping big money, this exhaust gives you a lot of value for the price. Yes — trade-offs exist (fitment quirks), but for the money and the immediacy of the audio/flow upgrade, it’s a solid pick.

Sounds pretty good for the price, way better than chopping off the muffler like some people do. I have headers on my car too so it gets alittle raspy above 4 to 5k rpms, but at idle and from 1 to 3k it has a nice throaty sound. Only complain is that it doesn’t sit exactly where the bumper cut out is for the pipe, it sits kinda crooked. Be prepared to fight rusted bolts on your car too, have a propane torch handy and make sure to use tons of pb blaster the day before and let it soak in and soak it again right before you go to wrenching on them, the rusted bolts will snap off and make life way more difficult than it should be.

The welds are good, no leaks, and it sounds amazing. The fitment was a bit off however. The shop I took it to for installation had to make some adjustments to get it to fit right, so you definitely get what you pay for. Overall, I would recommend this to anyone looking to make their car sound better without breaking the bank.

Put on my 1998 altezza 3GSE. Only used rear section since cat is welded to mid pipe. Fit well. Sounds surprisingly good. All hangers lined up. Sticks a bit past rear bumper but makes sense for japanese spec shorter bumpers. No regrets.

Fit perfectly, sounds great! It’s really not that loud at idle but once you give that throttle a little nudge, it definitely lets one know the power of the 2JZ

Pretty easy install the only problem is the mid pipe they give you does not fit on the cat, had to re-use the factory mid pipe. Other than that it sounded good it looked good proper placement and the bumper cap

Looks great sound great! But the fitment was horrible….Where the mid pipe connects to the end of your y pipe our OEM lexus has a little peice of medal hanging off so the after market has to open up alittle wider but it doesn’t do lucky I took my car to the shops and they cut that piece completely off so that the catback would sit flush the was its suppose to to.. and even then after everything bolted up drove home and the exhaust burned into my bumper badly… so when I got home I have to shave my bumper on one side completely just so the exhaust would fit without touching the bumper… because no matter what I did the exhaust would not budge to the right….

READ MY REVIEW
it’s great! Feels good to have an actual cat back exhaust after having a straight pipe for a while… The pros is that it comes with hardware and and a gnarly chrome cannon but it doesn’t like up well going out the bumper and you’ll have to do some minor modification to the cat to fit the bolts and gasket flush… in 2 weeks I now have an exhaust leak but it could just be me since I did the modifications
