will a 97 itr muffler bolt directly onto a 95 ls coupe w/o any modification?

 

I have a 98 itr stock muffler that's bolts perfectly onto my 98 ls....should be cool.

 

Yes, it is an axle back exhaust and will bolt right up.

 

did u use u'r stock piping with the itr muffler?

 

Without problema. But, think twice if you plan to add or have other mods.

I have a DC 4-1 JDM Header that is 2.5" and the ITR cat-back is 2.25". Now, I want the DC cat-back.

Good luck.

 

The ITR and LS mufflers and b-pipes fit the same. So, you can upgrade your LS with a Type-R muffler and/or b-pipe and it will just be a simple bolt-on replacement. I had to bend the heatshield on the underbody a little bit to keep it from hitting the Type-R b-pipe, but that's incredibly easy and I don't think it's a common problem anyways.

 

U gonna sell u'r itr catback if u get the DC one? IF so let me know..I'll take it.

 

Does the muffler sound any different or more agressive ?
Or is it a worthless mod???

 

I have one. I have CTR cams, I was running +2in +4ex for 26 deg of overlap on the GSR muffler and exhaust. I made the most power here. Once I put on the ITR muffler, I was able to run my overlap out to 34 with a slight bump at 4500rpm. Before I tried this with the GSR and it made a valley at 4500rpm and had a dead spot like the car wasnt acclerating until like 5500... I have +4, -2 in the cams now and it made great power at 18BTDC above 6K... not to mention everywhere else. yummy =) This led me to believe that the 98 ITR muffler flows much mo bedda. I like the fact that it is actually quieter than my stock 99 GSR one.
